It popped after 8, which is the new weekday standard. I know it's hard for APs to grasp, but when you're only buying a $44 ticket, that $20 parking fee looks like a big rip-off. Left around 12:30, TWD was still 90, AHS was still pushing 2 hours, even Ghost Town was at 40.
Further evidence of crowds, Tomb had to extend it's queue for a good 20 or 30 feet down the side road, past the floats.
I am curious to see how busy Saturday proves to be. Until 3 or 4 years ago, it would've been a lock that it was opened to FF guests. Doubtful this year, but some many other things going on around town that night, and tickets are at maximum price, I wonder if it gets all that busy.
